`3PECLF.C.t.'I0l\T forming part of Letters Patent N o. 732,052, dated June 30, 1903. Application liled October l5, 1900. Serial No. 33,103. (No model.)

To all w/"tont t may concern:

Be it known that I, JOHN F. DAVEY, of Beverly, county of Essex, and State of Massachusetts, have invented an Improvement in Peg- 5 ging-Machines, of which the following description, in connection with the accompany'- ing drawings, is a specification, like letters on the drawings representingr like parts.

The present invention relates to a peggingro machine,andis embodiedin an auxiliary feeding device for the material, the object of the invention being to relieve the awl of the lateral strain and at the same time to prevent disfiguring the sole of the shoe by usinga I5 roughened engaging surface to cooperate therewith in the feeding operation.

In pegging-machines ofthe type shown and described in Patent No. 581,066, granted April 20, 1897, to Davey and Ladd, the awl is zo mounted in a guide or carrier, which travels with the awl in the first downward movement thereof, during which the awl partially penetrates the stock, the feed movement then taking place and the awl then havinga furtherindependent downward movement with relation to the awl-carrier in order to completely penetrate the stock. These movements adapt the machine for use with a horn or support having a central perforation, and thus affording 3o the best possible support for the material, as is fully described in the patent above cited, to which reference may be made. For the reason, however, that the awl is thus movable in the guide the lateral, strain upon the awl in the feed movement soon wears the guideway loose, so that the awl in descending is not properly guided and is likely to engage the top of the horn and be bent or otherwise damaged instead of passing through the open- 4o ing in the proper way. This lateral strain has been partially relieved in some cases by forming at the end of the awl-guide a roughened or serrated surface, which grips the shoesole, and thus assists in carrying the same laterally, this, however, not eifectually remedying the evil and being objectionable, moreover, for the reason that it scars the shoe-sole, thus injuring the appearance thereof.

In accordance with the present invention 5o the machine is provided with alaterally-movable feeding member adapted to enter the material, said member being shown as asupplemental projection fixed in the awl-guide and substantially lhe same in shape as the awl itself, the distance between the said supplemental projection and the awl being equal to the feed movement. The said supplemental projection is not long enough to go completely through the-material; but when the awl and guide descend it will penetrate far enough to 6o have a firm hold, so that in thelateral movement it will carry the stock along, thus entirely relieving the awl from lateral strain. After the peg has been driven and the awl and awl-guide moved rearward laterally prior to the next preliminary punching operation the awl will stand directly over the opening made by the supplemental projection and will enter the same, so that no mark is left upon the shoe-sole, the pegs beingr driven where 7o the supplemental projection has previously entered.

Figure lis a front elevation of the head portion of a machine embodying the invention, the parts being shown in the positions in which they are in after the preliminary downward movement of the awl and prior to the lateral feed movement thereof. Fig. 2 is a detail, on an enlarged scale, showing the peg being driven and the awl and awl-guide up, 8o the parts being in the position in which they are in prior to the first downward movement of the awl. Fig. 3 is a similar view showing the parts in the position shown in Fig. 1, and Fig. 4 a similar view showing the parts just 85 after the lateral feed movement and prior to the final downward movement of the awl.

In the operation of the machine the awl a and awl-guide b first move downward from the position shown in Fig. 2 to the position 9o shown in Figs. 1 and 3, the awl then nearly but not quite penetrating the material A, so that the said awl does not project through the material so as to prevent the feed movement with relation to the horn B. The awlguide b at this period lies in contact with the upper surface of the material A, andthe awl and awl-guide then move laterally to theposition shown in Fig. 4, carrying the material with them. The horn is spring-pressed uplos ward against the material, and thus aords frictional resistance to the lateral movement, there being, therefore, a considerable lateral strain upon the awl,which in the ordinary construction tends to loosen the lit thereof in the awl-guide. To relieve the awl of such strain, the machine is provided in accordance with the present invention with a laterally-movable feeding projection b2, which is arranged to leave the material after its feeding movement has taken place at the point Where the awl is to operate, so that the hole left by the feeding projection is in position to receive the awl. As herein shown, the said feeding projection b2 is connected Wit-h theaWl-guide,

and as the said projection has no movement with relation to said awl-guide it can be firmly fixed therein, so that it has no tendency to work loose and is capable of bearing substantially all the lateral strain due to the feeding of the material, thereby relieving the awl of any tendency to Work loose in the awl-guide. The lateral movement of the awl and the lateral movement of the feedA member are the same, (in the construction shown the distance between the aWl and the feed member being equal to the length of the feed moveinent,) so that after the awl and awl-guide have moved back, as shown in Fig. 2, the opening left by the laterally-movable feeding projection b2 is directly under the awl, Which enters the same opening, so that no mark is left Where the feed member has penetrated the sole.

I claim- 1. In a pegging-machine the combination with the awl; of a feed member; means for moving said feed member longitudinally tol cause the same to penetrate the stock; and means for moving said member laterally to carry the stock to a position in which the openingmade by said member is in alinement with the awl.

2. In a pegging-machine, the combination with the awl and awl-guide, said parts being laterally movable to feed the material; of a supplemental projection rigidly secured to the awl-guide, the distance between the said projection and the awl beingequal to the length of lateral feed movement, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN F. DAVEY.
